The 24-year-old intelligence analyst is charged with aiding the enemy by causing hundreds of thousands of classified war logs and diplomatic cables to be published on the secret-sharing website WikiLeaks in 2009 and 2010.

The defense claims the government used unconstitutionally vague language in eight counts charging Manning with unauthorized possession and disclosure of classified information.

His lawyers say two other counts falsely allege that Manning lacked authorization to access computers linked to a Defense Department network used for classified information.
